Quantum critical nematic fluctuations and spin excitation anisotropy in iron pnictides
Chia-Chuan Liu, Elihu Abrahams, Qimiao Si
Quantum criticality in iron pnictides involves both the nematic and antiferromagnetic degrees of freedom, but the relationship between the two types of fluctuations has yet to be c…
Superconductivity at an antiferromagnetic quantum critical point: the role of energy fluctuations
Jian Kang, Rafael M. Fernandes, Elihu Abrahams +1
Motivated by recent experiments reporting superconductivity only at very low temperature in a class of heavy fermion compounds, we study the impact of energy fluctuations with smal…
Strong coupling theory of heavy fermion criticality II
Peter Wölfle, Jörg Schmalian, Elihu Abrahams
We present a theory of the scaling behavior of the thermodynamic, transport and dynamical properties of a three-dimensional metal governed by -dimensional fluctuations at a quan…
High Temperature Superconductivity in Iron Pnictides and Chalcogenides
Qimiao Si, Rong Yu, Elihu Abrahams
Superconductivity develops in metals upon the formation of a coherent macroscopic quantum state of electron pairs. Iron pnictides and chalcogenides are materials that have high sup…
Vertex functions at finite momentum: Application to antiferromagnetic quantum criticality
Peter Wölfle, Elihu Abrahams
We analyze the three-point vertex function that describes the coupling of fermionic particle-hole pairs in a metal to spin or charge fluctuations at non-zero momentum. We consider…
Spin-flip scattering of critical quasiparticles and the phase diagram of YbRh2Si2
Peter Woelfle, Elihu Abrahams
Several observed transport and thermodynamic properties of the heavy-fermion compound YbRh2Si2 in the quantum critical regime are unusual and suggest that the fermionic quasipartic…
